    Notizen: Abstract Neutron-deficient isotopes with Z=21 to 26 have been produced as projectile-like fragments of an intense58Ni GANIL beam of 69 MeV/nucleon. The nuclei selected by the upgraded LISE3 spectrometer were identified and implanted in a silicon detector telescope. The43Cr,47Fe and46Fe isotopes were identified for the first time whereas45Fe,45Mn,44Mn and42V were not observed, indicating probable instability of these nuclei against particle emission. Measurements of the half-lives of43Cr and46Mn have been performed and the analysis of their measured beta-delayed proton spectra has given, through the isobaric multiplet mass equation, an empirical estimation of their masses. Half-lives of44Cr,43V,47Fe and46Fe have also been measured. A discussion of various mass predictions for nuclei at the proton drip-line is given.

    Notizen: Abstract Secondary beams have been produced through interaction of a 1760 MeV Ar beam with a 99 mg/cm2 Be target. An achromatic spectrometer is used to select the magnetic rigidity corresponding to a given beam, and to transport this beam over a distance of about 18m. The beam purity is studied using a solid state ΔE-E telescope. Beams of38S and39Cl are produced with a purity of about 80%, and production rates of 1.5·10−6 I0 and 5·10−5 Io respectively. Here I0 denotes the primary beam intensity. Beams of38Ar,39Ar and41K are produced with about the same abundances as39Cl but with lower purities. It is shown that, by setting properly the experimental parameters, the beam production can be improved by a factor 2 to 5. This could lead to intensities of about 2·106 pps for38S, and of 107 to 108 pps for the four other beams. The possibility of purifying these beams by placing a degrader between the two dipoles of the spectrometer is shown experimentally.
